AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Not determinable from this photograph; darkening appears more consistent with natural oxidation, figure, or staining than proof of age.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and decorative panels.
Geographic Origin
Eastern and central North America, especially the United States.
Workability
Generally machines, sands, glues, and finishes well; irregular grain can cause localized tear-out. Pre-drilling is advisable for fasteners.
Finish Recommendations
Sand carefully and apply dewaxed shellac, oil, lacquer, or clear polyurethane; a clear finish will emphasize contrast. Test first for uneven absorption.
Notable Features
Strong contrast between pale and dark grain, attractive figure, and good dimensional stability; possible spalting or mineral streaking.
